I'm not sure I get your punchline.
(the question to a question..)

My question is:
In order to change the world, are atheists going to move together in a "localized" sort of way, which is often proposed on this website, and live closer together in all of its non-anonymous consequenses?

Many of the (atheist) hippies tried doing that in the '70s right? Ok, there were also a number of cult/communies in there too..

The only group that I see consequently living the ELP "doctrine" (smiley) is the Amish..

there are alot of Amish in my area and I eventually will write a story with pictures etc - really a fascinating culture and if the doomers are right then people will be learning some long lost techniques from the Amish. The guy I met was putting in a summer cooler in the side of a hill with some blocks of ice.

On that note however, the child mortality rate is extremely high (almost 50% I am told) Primary reason? Food poisoning, due to poor storage methods...
